Edible corn protein-based food packaging material and preparation method for same

Abstract

The invention provides edible corn protein-based food packaging material and a preparation method for the same and belongs to the technical filled of food packaging material. In the method, biamacromolecules / and high polymer material having nodal points and solvents are mixed to achieve mixed solution; then the mixed solution is injected into a reaction impeller; constant impelling flow speed of 0.5-50mL / h is maintained; static spinning voltage is 5-50kV; a positive electrode of voltage is connected to an outlet metal part of the reaction impeller; a negative electrode is connected to a filament receiver connected to the ground; a distance between the reaction impeller outlet metal part and the filament receiver is 5 to 50cm; the static spinning time is 0.5 to 24hours; and with the above steps, the corn protein-based food packaging material can be prepared. The invention further provides edible corn protein-based food packaging material prepared by the method. The preparation method is simple, raw material can be easily achieved and no harm is caused to human bodies; and demands of edibility, greenness and environment protection for packaging material can be met.

Description

technical field [0001] The invention belongs to the technical field of food packaging materials, and in particular relates to an edible corn protein-based food packaging material and a preparation method thereof. Background technique [0002] Zein forms an antiparallel structure with hydrogen bonds. The amino acid composition of Zein is relatively unique, and the molecules are connected by hydrophobic bonds, hydrogen bonds and limited disulfide bonds. It contains proline, leucine and Strong hydrophobic amino acids such as alanine and a small amount of polar amino acids such as glutamine, asparagine and glutamic acid lack basic and acidic amino acids, resulting in the unique solubility of zein.

Problems solved by technology

[0005] In the published literature reports, there is no relevant electrospinning method to prepare zein-based functional materials for application in the field of food packaging (embedding), and there is no report on the simultaneous embedding preparation of corresponding functional factors and protein-based functional materials.

At the same time, the synthesis and preparation conditions reported in the above literature are harsh and the process is complicated. At present, most of them stay in the laboratory stage and are far from meeting the technical requirements of industrial production.
